Biology covers half of the NEET Questions Paper. So, you should know the NEET 2022 Biology chapter wise weightage for preparing the NEET 2022 Biology Syllabus during NEET 2022 presentation.
NEET 2022 Biology Chapter wise Weightage
The exam paper of NEET-UG contains 200 MCQs from which 100 MCQs are came from only Biology subject. Biology has two parts : Botany and Zoology. The 100 Biology questions are divided into two sections : Section A and Section B. In Section A, 35 questions are asked from Botany and 35 questions are coming from Zoology. These 70 MCQs are mandatory that means you should attempt all 35 questions in each subject, Botany and Zoology. In Section B, 15 questions are asked from Botany and the other 15 questions are coming from Zoology. From these 30 questions, you should attempt any 10 questions out of 15 in each subjects : Botany and Zoology.
Here I have mentioned the NEET 2022 Biology Chapterwise weightage of the entire Biology Syllabus on the basis of previous years NEET Questions Paper (2013 to 2021) and the current pattern of NEET Biology Questions Paper from NTA (National Testing Agency). As the NEET 2022 Biology Syllabus is based on NCERT text book of class 11th and 12th, here I have distributed all the chapters unit wise as per NCERT text book.
